Edible films and coatings have received considerable attention in recent years because of their
advantages including use as edible packaging materials over synthetic films. This could contribute
to the reduction of environmental pollution. By functioning as barriers, such edible films and
coatings can feasibly reduce the complexity and thus improve the recyclability of packaging
materials, compared to the more traditional non-environmental friendly packaging materials, and
may be able to substitute such synthetic polymer films. New materials have been developed and
characterized by scientists, many from abundant natural sources that have traditionally been
regarded as waste materials. The objective of this review is to provide a comprehensive
introduction to edible coatings and films by providing descriptions of suitable materials, reviewing
their properties and describing methods of their applications and potential uses.
